COMBINED PULVERIZERJ CULTIVATOR, AND ROAD-SCRAPER.

SPECIFICATION forming part oi Letters Patent No. 350,762, dated October 12, 1886.

Application filed April 2, ISSG.

T0 all whom it may concern.-

.Be it known that I, Amish Nrlu'rAscHER, of Mendota, in the county of La Salle, andin the State of Illinois, have invented certain new and useful Improvements in Combined Pulverizer,Cultivator,and Road-Scraper; and I do hereby declare that the following` is a full, clear, and exact description thereof.

My invention relates to a combined pulverizer, eultivator, and road-scraper; and it consists in certain peculiarities of eonstruction,as will be fully described hereinafter with reference to the accompanying drawings,in which- Figure l represents a perspective view of my device in the form of apulverizer and cultivator; and Figs. 2 to l0, inclusive, detail views of various parts of my device.

Referring by letter to the drawings, A represents a rear cross-piece, B B side bars, and C a front cross-piece, said parts being suitably united to form the frame of my device. Hinged to the rear cross-piece,A,is a smoothing board or scraper,D,provided with suitable openings, a, through which pass upwardlycurved plates b, secured to the side bars, BB, each of these plates having a series of perforations adapted to be engaged by hooks c, pivotally connected to said smootl1ing-board,thus permitting the latter to be variously adjusted from a vertical toward a horizontal position, as may be found necessary or desirable.

'Io the front side of the smoothing board or scraper D is attached a plate, E, preferably of metal, having slots d, through which pass the securing-bolts e, thus permitting this plate to have a vibratory movement when the device is in operation, to prevent dirt sticking to the part D, said movement being caused by the uneven draft of the team, and is limited by stops f, that are designed to come against the rear cross-piece, A.

At the meeting-points of the rear crosspiece, A, and side bars, B B, I secure the ends of an ^-shaped brace-piece,G,having its apex connected to a sleeve, H, that is pivotally connected to the front cross-piece, C. This sleeve embraces a short tongue, I, a pin, g, forming a pivotal connection for said parts. The rear end of the short tongue I has secured thereto a housing, h, for a spring-bolt, t, the latter being designed to engage the perfor-ations Serial No. 197,497. (No model.)

in a vertical standard, F, so as to vary the adjustment of said tongue when the device is employed as a cultivator or pulverizer.

Near the forward end of the short tongue I is secured a suitably-braced vertical standard, K, to which is pivotally connected aseat-board, L,that has fastened thereto a plate, typrovided with an open slot, m, in the form of an obtuse angle. This plate forms a latch fora rackleVer, M, that extends up through the short tongue I, and has its lower end united to rods N, extending therefrom, and connecting a-t their other ends with elbows O, that are pivotally operative in adjustable socket-plates a a,bolted, respectively, to the side bars, B, and front cross-piece, C, at their points of j uncture, the horizontal portions of said elbows serving as hangers Afor sectional knife-bars l? when the machine is employed as a cultivator or pulverizer, and as axles for wheels Q when used as a road-scraper.

0, to aid in retaining the rack-lever M in the position to which it may be adjusted, and to relieve the latch-plate from the strain on this lever, caused by the draft oi.' the machine, I pivotally connect to the short tongue suitable wedge-plates, 1), that automatically adjust themselves to accomplish the desired result just specified.

The rack-lever llI is employed to regulate the double-tree It, that is connected to a ring, 1', at the lower end of said lever, and thus the draft thereon will regulate the depth of eut by the knives S, secured to the sectional bars I ,when the operator rides, andthe same effect can be had when the horses are hitched to a clevis, s, at the extreme front end of the short tongue I, and the operator walks.

If desired, a pole,l, may bev connected to the front end of the ytongue I when the ma.` chine is in use as a cultivator or pulverizer, and such a pole is always employed when the machine is converted to a scraper.

The two sections that compose each of the knife-bars P overlap one another, and are reflange, t t,as shown by Fig. 3. The top scc- If desirable, I may employ a wedgeblock,

spectivcly provided with a depending vertical ICO thereby forming a means for adjusting the` front ends of the knives S, that are provided with hooks w, that engage the perforations in the depending ange t of said top section. The knives S are severally provided with ar-ms S', that have their upper ends pivotally connected to a horizontal bar, U, and these arms have lugs .fr bolted to the perforated iiaugetof the lower knifebar section. The lower section of each knife-bar has a perforated upright, NV, secured to its outer end, and angular stay-rods X serve to adjustably unite said upA rights with perforated plates Y, rigidly connected to the outer ends of the rear crosspiece, A.

By the construction andl arrangement of parts just described the knives can be' readily adjusted as to inclination and depth of out. The sections composing the knife-bars l? and the horizontal bar U being severally provided with a series of perforations, the knives S can be readily adjusted to vary the width of space therebetween.

To convert the pulverizer or cultivator to a scraper,the knife-bars P are removed and the elbows O swung around to be in line with the length of thc front crosspiece, C. Wheels Q are now placed on the horizontal portions of the elbows, the front ends of the stay-rods X placed thereonj ust back of the linchpins, to

hold said elbows stationaryv in the position to which they have been adj usted. rlhe machine is now complete as a scraper for cleaning out ditches or other work in line with the draft.

To convert the machine to a roadscraper the elbows O are swung around so as to be inline with the length of the side bars, B, or at right angles to the position they were in when operating said machine for scraping in the line of draft. The stay-rods X are unhooked from the plates Y and carried round to engage eyes projecting from the front cross-piece, C, beneath the tongue I, thus acting to retain said elbows in this new position. The pole T and tongue I are now swung around in either direction until said tongue comes against a vertical part, y, of the Ashaped brace G, thus placing the smoothing-board (or scraper proper, as it may now be termed) at an angle to the line of draft.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the main frame, of a vertical standard centrally secured to the rear of said frame, and having a series of perforations, a tongue pivotally connected to the front of the frame vand transversely extended across the latter, and a suitable bolt operatively secured to the rear end of the tongue to engage the perforations in the standard, ac-

cording to the adjustment of said tongue, as set forth.
